K-Line MP-15 CC Lite upgrade

Just for kicks, have you tried wiring the motors in series instead of parallel? I do this with K-Line diesels and it helps a lot with low speed performance.

You might want to take a look at a previous thread on this very topic. I believe it will answer your question.

Thanks Milwrd, 

Actually that thread is the reason I decided to reverse my upgrade so quickly.  I started my upgrade about the same time, read it with interest, and tested my MP-15 using the "turning the drive train" test mentioned in the posting.   I could feel the "ratcheting" in the MP-15 drive trucks, so I wasn't surprised with the outcome.  Still going through the installation and upgrade was a learning experience.

Rob - thanks for the suggestion, I tested with both parallel and series, series was the winner, but still not great.  Parallel was terrible, for a moment I thought the two motors were running in opposite directions!  As you might know, standard on this K-Line is a sliding switch to select either series or parallel when running conventional.

I had the same experience with the RMT RDT, which is a very similar motor and drive train.  It was like a bucking bronco, it was NOT a happy camper!

Yes, the last productions of the MP15 with the horn had the DPDT slide switch, which should have been standard from the start on all of the dual motored diesels(and should be on all Williams & WBB 2 motored diesels too). I wasn't sure if you had preserved this with the conversion.
